We have touched upon the importance of the condylar
postion as a goal. To reiterate: The goal is to have the
teeth hit simultaneously when the condyle is seated in
an anterior superior postion on the disc centererd
transversely. The condyles and the discs move together
down the eminentia from their uppermost position in the
fossae as the jaw opens. If disc displacement is
complete or even partial the disc, condyle, and fossa
undergo degenerative changes. This results in a change
of how the condyle moves which, together with changes in
jaw position result in adverse changes to the profile (ie
the mandible appears to drop backwards and an open bite).
